I have made a PCB with CYUSB3014, when doing test, about 2/3 boards can link to usb3.0 and works very well, I can get 430MB/s use the streamer program with no error.

but about 1/3 boards can only link with usb2.0, only 40MB/s with streamer program.

I have checked the clock, power, sstx/ssrx connections on board, seems all good.

Do you have any idea, how to check this issue?

Thanks a lot.

Questions about EEPROM of CYUSB3014 for booting.

The AN76405 Boot Options document contains a list of EEPROM-tested vendors as shown below.

Currently, EEPROM is being reviewed as a smaller package due to the PCB size limitation of the oral scanner model being developed by our company.

I excluded the BGA Type and checked it and found ONSEMI's CAT24M01HU5I−GT3.

Please check if there are any problems when using onsemi eeprom.

Hi all,

I am stuck for a few days with this issue:

To begin with, my setup is the following:

Altera Cyclone V attached through GPIF 2 interface to FX3, which is connected to a windows desktop through USB 3.0 cable.

I validated the system with application note: 001-65974_AN65974_Designing_with_the_EZ-USB_FX3_Slave_FIFO_Interface

The only difference is that, my FPGA is the Cyclone V and the appnote was made to Cyclone III. Just made the porting and everything was up and running.

On the FPGA side, I just merged the two examples of streamIn and streamOut, because I wanted the system to be bidirectional. And when generating data to send to the desktop I was incrementing it, to be as follows: 32'd0000_0000, 32'd0000_0001, 32'd0000_0002, 32'd0000_0003, etc etc etc

On the FX3 is running the SlaveFIFOsync.img which setups the DMA to dispatch data in AUTO mode with two sockets.

On windows desktop I am using the streamer demo from cypress, to measure the XferRate and to watch the data coming through the USB 3.0.

Now, the issue is:

If I select one packet for transfer, I can see the data coming correctly like this:

32'd0000_0000,

32'd0000_0001,

32'd0000_0002,

32'd0000_0003,

....

If I select two packet for transfer, I can see the data coming correctly like this:

32'd0000_0000,

32'd0000_0002,

32'd0000_0004,

32'd0000_0006,

....

If I select four packet for transfer, I can see the data coming correctly like this:

32'd0000_0000,

32'd0000_0004,

32'd0000_0008,

32'd0000_000C,

....

I dont want to use just one packet for Xfer because the Xfer rate is xtremely low.

Maybe the data sampling on the streamer app is being done wrong. I think it is only printing the last 32-bit packet of each Xfer. I cannot access to all the packets in the Xfer.

Can anybody help me on this issue please ?

Thanks in advance,

Pedro

Hi,

We are working on a solution that involves transmitting 5120x720 video at 60fps, from FPGA through FX3 (32-bit parallel interface) to PC (USB3)

Each pixel size is 8-bit and since UVC does not support raw image data we want to convert the 8 bit pixels to 16 bit pixels by apending a color byte 127 (which means grayscale in YUV format). We want to perform this conversion in the FX3 before transmitting the data to the PC

That way our RAW 8 pixels from FPGA will be converted to YUV format and we can view the video on the PC through UVC.

Is this possible? If not, what is an alternative way viewing the data on the PC without using a custom windows driver.

Thanks,

Hi,

I'm starting a new product with CYUSB3014 FX3 chip.

My simple question is, how many devices I am allowed to put to the market, using Cypress default PID/VID, before having to purchase my own VID ?

My target market is not a consumer market, and 200 devices per year is the maximum number of devices I expect to manufacture in the first couple of years, So it would be very helpful if there was a way to kickstart the project with the defaut PID/VID.

Some other manufacturers (like NXP) provide custom PID to be used with their VID, and limited to a few thousands devices. Do you happen to offer a similar service?

Thank you,

I need to generate clock with frequency changing between 2MHz and 2.2MHz in every 10 periods. I could generate the clean PWM with

    gpioComplexConfig.outValue    = CyFalse;
    gpioComplexConfig.inputEn     = CyFalse;
    gpioComplexConfig.driveLowEn  = CyTrue;
    gpioComplexConfig.driveHighEn = CyTrue;
    gpioComplexConfig.pinMode     = CY_U3P_GPIO_MODE_PWM;
    gpioComplexConfig.intrMode    = CY_U3P_GPIO_NO_INTR;
    gpioComplexConfig.timerMode   = CY_U3P_GPIO_TIMER_HIGH_FREQ;
    gpioComplexConfig.timer       = 0;
    gpioComplexConfig.period      = (93-1);
    gpioComplexConfig.threshold   = (47-1);

    status = CyU3PGpioSetComplexConfig(GPIO_42, &gpioComplexConfig);

But when I use the interrupt as:

gpioComplexConfig.intrMode = CY_U3P_GPIO_INTR_TIMER_ZERO;

I start to get jitters in the clock:

even when the callback function is empty.

I tried to use CyU3PGpioComplexUpdate() in the callback to change the period,

void onCallback(uint8_t gpio_id) {
            g_timerIntrCount++;
        
            if (g_timerIntrCount == 20){
                CyU3PGpioComplexUpdate(gpio_id, 46, 92);
                g_timerIntrCount = 0;
            }    
            else if (g_timerIntrCount == 10){
                CyU3PGpioComplexUpdate(gpio_id, 46, 93);
            }
}

but the jitters still occur. How can I solve this issue?

Hello

It is described about  "CYUSB3012 and CYUSB3014 Pin List"  in the FX3 datasheet.
However, the BGA pin numbers are blank in some places.I will attach the example with red frame part.
How should I understand the blank pins?

Best Regards

Hi,

I am facing some unusual issues with my CX3. When I start streaming using the host app some of the frames in starting are not proper. After 15-20 frames it runs ok for quite some time. I have attached teraterm log for the same. I am attaching MIPI configuration and schematic of MIPI portion for the same. Let me know if I am unclear somewhere.

Thanks in advance.
